B. Helen should have added 17 to both sides of the equation.
When trying to solve an equation like that with a variable, you have to make sure both sides are even. Whatever you do to one side, you have to do to the other. So, if you add 17 to one side to cancel it out, you have to add 17 to the other side as well.
